文章回顾了我国国防支出对经济增长影响的有关文献,比较分析了揭示这种影响正负的需求-供给、外部性、公共产品三种主流模型以及它们背后隐藏的原因,得出了我国国防支出政策应以适度增长为根本原则、最大限度地减少非理性支出、合理有效配置国防资源、大力引导和支持军民通用型发展道路的启示。 This paper reviews the literature on the impact of national defense expenditure on economic growth, compares and analyzes the three major mainstream models of supply and externalities and public goods, and reveals the hidden causes behind them. Policies should be based on modest growth as the fundamental principle, minimize irrational expenditures, rationally and effectively allocate national defense resources, and vigorously guide and support the military-civilian general-type development path.
